The DLC Bike Mount for GoPro Cameras from Dot Line features an adjustable clamp opening from 0.6" to 1.25". The inside of the clamp uses a rubberized, ribbed surface to help firmly secure the mount to the bar of the bike and to help protect its surface. The adjustment handle for the clamp size folds out of the way when not in use. The top of the clamp features a 180° tilting head which uses a saw-tooth style locking mechanism to assure secure positioning of the camera. This Bike Mount is suitable for all GoPro cameras.
